How to import¶
from esmerald import JWTConfig
Bases: BaseModel
An instance of JWTConfig.
This is a configuration that should be used with a dependency and for that reason you must run first:
$ pip install esmerald[jwt]
This configuration is passed to the CORSMiddleware and enables the middleware.
Example
Note
This following example will build an auth middleware and it will be using the Esmerald contrib version.
You are free to ignore this and build your own.
from esmerald import Esmerald, settings
from esmerald.config.jwt import JWTConfig
from esmerald.contrib.auth.edgy.base_user import AbstractUser
from edgy import Database, Registry
database = Database("sqlite:///db.sqlite")
registry = Registry(database=database)
class User(AbstractUser):
'''
Inheriting from the the contrib user for Edgy.
'''
class Meta:
registry = registry
jwt_config = JWTConfig(
signing_key=settings.secret_key,
)
auth_middleware = StarletteMiddleware(
JWTAuthMiddleware, config=jwt_config, user_model=User
)
app = Esmerald(middleware=[auth_middleware])
instance-attribute
¶
signing_key
The secret used to encode and generate the JWT Token. Having a centralized secret like in the settings would be recommended as it would be the source of truth for any configuration needing a secret.

¶
api_key_header = 'X_API_TOKEN'
API Key header for the jwt.
class-attribute
instance-attribute
¶
authorization_header = 'Authorization'
Authorization header name.
class-attribute
instance-attribute
¶
algorithm = 'HS256'
Algorithm used for the jwt token encoding/decoding.

instance-attribute
¶
access_token_lifetime = timedelta(minutes=5)
Lifetime of the token after generation.
class-attribute
instance-attribute
¶
refresh_token_lifetime = timedelta(days=1)
Lifetime of the generated refresh token.
class-attribute
instance-attribute
¶
auth_header_types = ['Bearer']
Header to be sent with the token value.

instance-attribute
¶
jti_claim = 'jti'
Used to prevent the JWT from being relayed and relay attacks.
class-attribute
instance-attribute
¶
sliding_token_lifetime = timedelta(minutes=5)
A datetime.timedelta object which specifies how long sliding tokens are valid to prove authentication. This timedelta value is added to the current UTC time during token generation to obtain the token's default exp claim value.
class-attribute
instance-attribute
¶
sliding_token_refresh_lifetime = timedelta(days=1)
A datetime.timedelta object which specifies how long sliding tokens are valid to be refreshed. This timedelta value is added to the current UTC time during token generation to obtain the token's default exp claim value.

instance-attribute
¶
user_id_field = 'id'
The database field from the user model that will be included in generated tokens to identify users. It is recommended that the value of this setting specifies a field that does not normally change once its initial value is chosen. For example, specifying a username or email field would be a poor choice since an account's username or email might change depending on how account management in a given service is designed. This could allow a new account to be created with an old username while an existing token is still valid which uses that username as a user identifier.

instance-attribute
¶
user_id_claim = 'user_id'
The claim in generated tokens which will be used to store user identifiers. For example, a setting value of 'user_id' would mean generated tokens include a user_id claim that contains the user's identifier.

¶
access_token_name = 'access_token'
Name of the key for the access token.

instance-attribute
¶
refresh_token_name = 'refresh_token'
Name of the key for the refresh token.
